stage 2 na crower cam experience
well after 3 days of hard work i have my clutch installed arp wheel studs in and finnaly today crower stage 2 cam and spring kit in. I invite anyone with a stage 2 cam installed to post thier experiences (boosted or otherwise) here.
Idle is rough I would call it more than "slighlty lopey at idle" I believe there will be some smoothing out with AEM ems but with just vafc2 I would call it more than lopey. I have to say it does sound cool. Hot rod ish.
My cam gear is set to 2 degrees advance...i just left it as i had it before. I may experiement with it in the near future. I will post results here. Sorry but there is no before dyno. you will have to look at the last dyno i had, many mods back. and take my wod that I was putting around 130 ish whp to the ground. 60 bux is 60 bux. I will post the final dyno when it happens. Untuned it barks third gear on command < may have to do with the clutch I just put in. It pulls slightly harder than before. dare I say it.... I felt vtec kick in when at partial throttle.
It is obvious to me that there is alot of tuning to be done. It is noticable louder than before. I will street tune my AF ratio as much as I can with my wiideband. At partial throttle the af ratio is all over the place. < there is not much you can do about this with just vafc2. The stock ecu adjusts quite a bit. I am starting to look at EMS as my next mod. When I started my obsession with making na d17 hp I never thought it would go this far. My k swap looks so far away now. I keep thinking "maybe I will be satisfied with just this" ...NOT. Stay tuned It has just been a few hours since the install and I have only driven it a couple times. More to come.

thats weird.... i know the ems or e-manage is so much better but my neighbor has a b16 swap with 75 shot, skunk2 stg2 cams, i/h/e etc tuned with vafc and my friend with a DA teg has a b20 bottom and a ls head with crower stage 3 cams and he tunes it with the safc and there air/fuel is pretty good but u can hear the cams especially at idle. I am pretty sure ur air/fuel will be much better when tuned at a dyno. I also see quite a few people use the vafc or safc with dsm injectors tuned on 8 psi turbo setups so u should be fine, but if u got the coin for the ems deff do it. That would be sic to see a d17 with full pistons, rods, ems, cam, and with a lil bit of nitrous get in the high 200 hp range. Good luck.
I'm sure with the ems, you'd be able to take a good advantage of the cam ... with the stage 2, I'm assuming you also have the valve springs/retainers?
hello 8k redline?

yup sprimgs and retainers are in there. I would not raise the redline untill I have ARP rod bolts... at the least, installed. A tuned dyno will tell where the power is at. Time to call some shops and get a price on tuning. A ride ...sure when its running as good as it can. I have yet to try spray thru it. I want to know where my timing is at.

Great info in the first post...cannot wait for mine!! I am not wanting crazy power (obviously) will it be ok tuned with the VAFC?? Opinions on this??

I don't think that the stage 2 cam is for everybody. There is definatly a sacrafice in drivability. The idle is rough and it actually cuts off once in a while. You can't just stomp on the gas and go. you have to feather it up to 2k and then its cool. I personally think that vafc2 and a cam gear is not going to cut it. I'll haVe to get it tuned by a pro to find out for sure. I think that e manage with the ignition harness would be minimal to get this cam to idle better and probably perform better. < this is only a guess since no one has tried it yet. I'll monkey around with it for a week or two then take it somewhere.

Like I said in another thread I think the only right way to use this cam is with EMS. I am going to have one installed and tuned hopefully by Aug18th. I have the Stage 2 with Vafc also and it just ain't right. The ECU makes idle jump around and once it settles at 800 (stock idle ) it is hella rough and does feel like cutting off... DJmota I had to put my VAFC @ -29 at 1000 to get it to idle withough cutting off...was flooding it at first. I agree with DJmota tho it ain't for everyone. If you want the "slight lope at idle" them get the EMS at $1500ish ...that is the ONLY way it will run right.

is the new ems that you don't have to run an extra switch for ac available yet? How much are you paying for the ems?

i think once you get it tuned up it wont stall on you or anything. just my thought.

oK small update. Fuel at WOT is close to where I want it, not exactly but close. The vafc2 will not give me any more fuel. I believe the stock fuel map is maxed out. Idle is still rough although it does not die on me anymore. I had fuel setting on the plus side at idle. I think this retarded the timing and made it hard for the ecu to keep it idling. I set it to zero and it helped a tiny bit. It pulls nicely. Playing with the cam gear is next. I am hoping it helps the idle more and helps the 1000-2500 rpm range more hospitable. I think I see AEM EMS in my future. Once my clutch is broken in I will try the spray.

sorry but I don't have the means to gte a clip or a vid. I use the computer and camera at work. Maybe i'll try to show up to a local meet and another member could hook it up.

I love the lumpyness to.
I was at the track and a mustang guy with super lumpy cams, looked over at my car sputtering away( i had the cam gears adjusted so it wouldnt idle for my than 20 seconds by itself) and said" its funny cause your car sounds worse than mine
, it puts a huge smile on ur face when u sound like a harly. Have fun tuning, u can probably squeeze 4-5 more hp outa the cams with SUPEr agressive tuning. Thread Starter

I Played with the cam gear this weekend. tried advancing it 2 more degrees +4 idle felt the same if not a little worse performance and AFR unchanged also gave me a CEL after a day or 2. gave it a shot at 2 degrees retard and to my surprise the AFR went richer than it was in the past. I believe that I was wrong previously about being axed out. I now think that with the adv settings I had the intake valve closing too soon and not letting in the full air/fuel charge get in the cylinder. It "feels" better when I am on it but that could be just my head. It does bark third better now
Idle is the same and it gave me another cel this morning.
I am going to try it at zero to see what happens there next. I know I need a dyno to really tell me whats going on but I am just experiementing and learnig at the same time. I am going to try and make it this tuesday to the local 714 meet. and maybe even to the one in cerritos this weekend. It been a while since I showed up to an event. IMO I still need EMS.

The new one is not out yet. Supposedly it will be the next ems realeased but who knows when that will happen. When it does I plan on picking it up. Small update. I dorve my car to las vegas from LA And got a cel that does not go away with resseting the ecu. Now my idle stays at 1500rpm. Also something wierd when I let off the gas to decelerate the ecu does not cut off fuel like it did before. I think I am in a sort of limp mode ignition map. It still revs all the way up but just not quite as fats as before. I think Its time to pick up an obd2 scanner.

scanned the cel it has nothing to do with the cam. low tps voltage. turned out to be a broken wire where I tapped for my n20
It did not run too bad with no tps.

supposed to be the 30-1030 which is supposed to fix the AC problem...that is what I was told at least...guess we will find out. think it was the 30-1070 that you had to rewire the ac.

I had to take an unexpected trip to new mexico this weekend in the vic. 800 miles one way. No problems whatsoever. for those wondering about gas milage. I got 35.7 miles to the gallon hwy doin about 85 all the way.
I was pretty impressed that it still get good milage.
